Targetting Monocytes With Microparticles To Prevent Kidney Allograft Rejection

Summary
Whilst transplantation is lifesaving for many Australians with organ failure, it is a treatment rather than cure as recipients are dependent upon lifelong immunosuppression to prevent transplant rejection. Risks of death due to infection and cancer therefore remain high. We will test a new strategy in mice which modifies recipients of monocytes at the time of transplantation, to enable them to accept and tolerate the organ without ongoing need for expensive and dangerous immunosuppressive drugs.
TOLERANCE OR REJECTION – THE ROLE OF INNATE IMMUNITY IN DETERMINNG THE FATE OF A KIDNEY ALLOGRAFT

Summary
Transplantation is the optimal management for people with organ failure. Tolerance, to retain transplant function without immunosuppression, remains the key goal but is seldom achieved. We propose to block Toll-like receptor signalling to achieve kidney transplant tolerance in mice. If successful, we would translate this into clinical trials in human, seeking to achieve organ transplantation without the risks of cancer, infection and premature death that are currently faced by organ recipients.
Conquering The Final Frontier In Lung Transplantation - Mesenchymal Stromal Cell Therapy For Chronic Lung Allograft Dysfunction

Summary
Lung transplantation remains the only treatment option for an increasing number of Australians with end-stage lung disease, however long-term outcomes are severely compromised by the almost universal development of chronic rejection. Mesenchymal stromal cells (MSCs) hold great promise in treating rejection, and in a world-first we have recently demonstrated that this approach is safe. In another world-first, this randomized, controlled study will determine whether MSC therapy is effective.
Mechanisms Of Islet Graft Rejection And Acceptance

Summary
Islet grafts offer diabetic patients the promise of a return to insulin-independence. In this project we will study how natural regulatory T cells suppress islet graft rejection in a mouse model. We will determine where regulatory T cells interact with graft-rejecting T cells, and define the mechanisms used to mediate their suppressive effects. Our findings will aid in developing new ways to induce long-term acceptance of islet grafts without immunosuppressive drugs.
IL-6 As The Key Inflammatory Mediator Controlling GVHD

Summary
Allogeneic haematopoietic stem cell transplantation (SCT) is a curative treatment for blood cancers. Graft-versus-host disease (GVHD) is a major limitation which occurs when the newly transplanted immune system mounts a rejection response against the recipient and is responsible for the death of up to 40% of transplant recipients. These studies will optimize a new approach to prevent GVHD focusing on a protein called interleukin-6. Ultimately, it is anticipated such approaches will improve the o ....Allogeneic haematopoietic stem cell transplantation (SCT) is a curative treatment for blood cancers.
